Entry Lighting
This feature turns on the courtesy lamps and the
backlighting to the door switches and to the exterior
lamp control when a door is opened or if you press
the remote keyless entry transmitter unlock button.
If activated due to the transmitter, the lighting will
remain active for about 40 seconds. Since the entry
lighting system uses the light sensor, it must be
dark outside in order for the courtesy lamps to turn
on. The courtesy lamps turn off approximately
25 seconds after the last door is closed. They will
dim to off if the ignition key is turned to RUN, or
immediately deactivate if the power locks are
activated.
Parade Dimming
This feature prohibits dimming of the digital
displays and backlighting during daylight hours
when the key is in the ignition and the headlamps
are on. This feature is fully automatic. When
the light sensor reads darkness outside and the
parking lamps are active, the digital displays
can be adjusted by turning the instrument panel
brightness knob counterclockwise to dim and
clockwise to brighten lighting.
Reading Lamps
The reading lamps are located on the overhead
console on the headliner and in the rear door
opening. These lamps come on automatically
when any door is opened and it is dark outside.
For manual operation, press the button to
turn them on. Press it again to turn them off.
If the reading lamps are left on, they automatically
shut off 10 minutes after the ignition has been
turned off.
Battery Load Management
The battery load management feature is
designed to monitor the vehicle’s electrical
load and determine when the battery is in a
heavy discharge condition. During times of high
electrical loading, the engine may idle at a higher
revolutions per minute (rpm) setting than normal
to make sure the battery charges. High electrical
loads may occur when several of the following are
on: headlamps, high beams, fog lamps, rear
window defogger, the climate control fan at high
speeds, heated seats and engine cooling fans.

Inadvertent Power Battery Saver
This feature is designed to protect your vehicle’s
battery against drainage from the interior lamps,
trunk lamp, glove box lamp, or the garage door
opener. When the ignition is turned off, the power
to these features will automatically turn off after
10 minutes. Power will be restored for an additional
10 minutes if any door or trunk is opened, or the
courtesy lamp switch is turned on.
Battery Run-Down Protection
This vehicle has a feature to help prevent the
battery from being drained, if the interior courtesy
lamps, reading/map lamps, visor vanity lamps
or trunk lamp are accidentally left on. If any
of these lamps are left on, they will automatically
turn off after 10 minutes, if the ignition is off.
The lamps will not come back on again until
one of the following occurs:
The ignition is turned on.
The exterior lamps control is turned off, then
on again.
The headlamps will time out after 10 minutes,
if they are manually turned on before the ignition
is off.
Ultrasonic Front and Rear Parking
Assist (UFRPA)
If your vehicle is equipped, the Ultrasonic Front and
Rear Parking Assist (UFRPA) system is designed
to help you park. It operates only at speeds less
than 5 mph (8km/h). UFRPA helps make parking
easier and helps you avoid colliding with objects
such as parked vehicles. The UFRPA system
detects objects that are close to the vehicle which
are at least 10 inches (25.4 cm) off the ground and
below hood or trunk level. The system detects
objects up to 4 feet (1.2 m) in front of the vehicle
and up to 8 feet (2.5 m) behind your vehicle.
UFRPA determines how close these objects are
from your bumpers within this area. Four ultrasonic
sensors on the front and rear bumpers are used to
detect the distance to the object.
202

A bicycle or an object is attached to the front
bumper during your last drive when you turned
off the vehicle. If the attached objects are
removed from your vehicle before the start of
your next drive, the system will return to normal
unless an object is detected when the vehicle is
shifted out of park. If this occurs, UFRPA will
return to normal operation when the vehicle is
driven forward above 15 mph (25 km/h).
The ultrasonic sensors are not kept clean.
So be sure to keep your vehicle’s front and rear
bumpers free of mud, dirt, snow, ice and slush.
For cleaning instructions, seeWashing Your
Vehicle on page 444. If after cleaning the front
and rear bumpers and driving forward at a
speed of at least 15 mph (25 km/h), the DIC
displays the PARKING ASSIST OFF message,
see your dealer/retailer.
Other conditions that may affect system
performance include vibrations from a
jackhammer or the compression of air
brakes on a very large truck or other
mechanical devices that interfere with
UFRPA performance.
When UFRPA is disabled without driver action
and the driver attempts to turn UFRPA back
on using the Driver Information Center (DIC),
the PARKING ASSIST ON option will not be
selectable if the necessary conditions stated
above for normal system operation are not met.
As always, drivers should use care when backing
up a vehicle. Always look behind you, being
sure to check for other vehicles, obstructions
and blind spots.
For Driver Information Center messages related
to UFRPA, seeDIC Warnings and Messages
on page 246.
If the bumper is damaged, your UFRPA system
may not work properly. Take the vehicle to
your dealer/retailer to repair the system.

Automatic Operation
AUTO9(Automatic Fan):When this position
is selected on the fan control, the system will
adjust the fan speed. If the OnStar
®system
is activated when this position is selected,
the climate control fan speed will lower.AUTO (Automatic Mode):
1. Turn the fan control to the AUTO position.
2. Turn the mode control to the AUTO position.
3. Adjust the temperature to a comfortable
setting between 68°F (21°C) and 78°F (26°C).
Choosing the coldest or warmest temperature
setting will not cause the system to heat or cool
any faster. In cold weather, the system will start
at reduced fan speeds to avoid blowing cold air
into your vehicle until warmer air is available.
The system will start out blowing air at the oor
but may change modes automatically as the
vehicle warms up to maintain the chosen
temperature setting. The length of time needed
to warm the interior will depend on the outside
temperature and temperature of the vehicle.
4. Wait 20 to 30 minutes for the system to
stabilize in order for the system to regulate
automatically. Then adjust the temperature
as necessary to nd your comfort setting.
Do not cover the solar sensor located in the
center of the instrument panel near the windshield.
For more information on the solar sensor, see
“Sensors” later in this section.
Dual Climate Control System for Vehicles with
Rear Climate Control

will come on automatically, as necessary.
The air conditioning system removes moisture from
the air, so you may notice a small amount of water
dripping underneath your vehicle while idling or
after turning off the engine. This is normal.
Sensors
The solar sensor, located in the defrost grille,
middle of the instrument panel, monitors the solar
radiation. Do not cover the solar sensor or the
system will not work properly.
214

There is also an interior
temperature sensor
located next to the
steering wheel that
measures the
temperature of the air
inside your vehicle.
There is also an exterior temperature sensor
located behind the front grille. This sensor reads
the outside air temperature and helps maintain
the temperature inside the vehicle. Any cover
on the front of the vehicle could cause a
false reading in the displayed temperature.In order to prevent false temperature readings
at start up, the displayed temperature will
not change until the following occurs:
Vehicle speed is above 10 mph (16 kmh) for
5 minutes.
Vehicle speed is above 32 mph (51 kmh) for
2 and a half minutes.
The climate control system uses the information
from these sensors to maintain your comfort
setting by adjusting the outlet temperature, fan
speed, and the air delivery mode. The system may
also supply cooler air to the side of the vehicle
facing the sun. The recirculation mode will also
be used as needed to maintain cool outlet
temperatures.
215

Airbag Readiness Light
There is an airbag readiness light on the instrument
panel, which shows the airbag symbol. The system
checks the airbag’s electrical system for
malfunctions. The light tells you if there is an

go out. This means
the system is ready.
If the airbag readiness light stays on after you
start the vehicle or comes on when you are driving,
your airbag system may not work properly.
Have your vehicle serviced right away.{CAUTION:
If the airbag readiness light stays on after
you start your vehicle, it means the airbag
system may not be working properly. The
airbags in your vehicle may not inate in
a crash, or they could even inate without
a crash. To help avoid injury to yourself
or others, have your vehicle serviced right
away if the airbag readiness light stays on
after you start your vehicle.
The airbag readiness light should ash for a
few seconds when you turn the vehicle on. If the
light does not come on then, have it xed so it
will be ready to warn you if there is a problem.
